SIPECIFICATION forming part of Letters Patent No.`735,158, dated August 4, 1903.

Application filed April 4, 1903. Serial No. 151,090. (No modeLl To all whom, t may concern.-

Be it known that I, ALBERT G. SCHMIDT, a citizen of the United States,residing at Springfield, in the county of Olark and State of Ohio, have invented certain new and useful Improvements in Molders Sponges, of which the following is a specification.

My invention relates to an article for molders use, and more particularly to a compressible article having an absorbent or celllike body capable of retaining liquid in like manner as a molders sponge used in foundry practice.

Molders require in their work a small sponge, preferably conical in form or of such shape that a portion of it terminates in a point. The natural supply of sponges adapted for the purpose is so limited that they do not meet the demand, and therefore command a high price. Y

The object of my invention is to provide an article of suitable material and structure that will answer the purpose and can be supplied at a reasonable cost.-

My invention consists of the constructions and combinations hereinafter described, and set forth in the claims.

In the accompanying drawings, which form a part of this specification, Figure l. represents an article embodying my invention. Fig. 2 is a sectional viewof same, showing an interior stay or stitch to assist in preserving the conical form; and Fig. 3 is a similar view showing a modified form of stitches for preserving the conical form.

Like parts are represented by similar letters of reference in the several views.

In constructing the article I employ any suitable, absorbent material capable of retaining liquid until by compression -the liquid is made to flow out; but on account of its adaptability for the purpose and economy in its use I preferably employ waste pieces of sponge, which I envelop in a suitable cover of pliable porous material, preferably a netting. The envelop is so formed and the Sponges assembled therein that the article is preferably cone-shaped, as that yform is best adapted to meet the requirements of its use, although any shape, a portion of which terminates in a point, will be within the spirit of my invention.

In the drawings I have shown the article substantially cone-shaped in form, a cover d being sewed, knitted, or otherwise secured about the sides a of the cone. A plurality of small sponges or waste pieces of sponge a2 constitute the cone, and to assist in keeping the article cone-shaped I preferably use a thread or cord through the pieces of sponge and secure the same to the crown, as shown in Fig. 2, or stitches may be taken through the sponge and secured to both the crown andV side walls, as shown in Fig. 3, or the stitches may be omitted entirely without deviating from the spirit of my invention. As thus prepared after it is saturated with water the article is compressed by hand, the water flowing from the point of the cone.

Having thus described my invention, I claiml. In an article of manufacture, a pointed conical absorbent body of such dimensions as to render it capableof delivering liquid in a linestream to a particular spot in a sand mold. Y

2. In an article of manufacture,`a pointed conical absorbent body consisting of a plurality of pieces secured together, said body being of such dimensions as to render it capable of delivering liquid in a fine stream to a particular spot in a sand mold.

3. In an article of manufacture, a pointed conical absorbent body consisting of a plurality of pieces, said body being of suitable dimensions for the purpose specified, and a pliable porous envelop for said body, substantially as specified.

4:. In an article of manufacture, a pointed conical absorbent body consisting of a plurality of pieces, said body being of suitable dimensions for the purpose specified, apliable porous envelop for said body and means engaging said body and secured to said envelop to hold said body in its conical form, substantially as specified.

5. In an article of manufacture, a pointed conical-shaped net, of suitable dimensions for the purpose specified, and a filling therefor consisting of a plurality of Sponges, substantially as specified.

6. In an article of manufacture, a conical absorbent body consisting of a plurality of Sponges and a net to envelop and hold said IOO body in its conical forrn, for the purpose In testimony whereof have hereunto set specified. my hand this 31st day of March, A. D. 1903.

7. In an article of manufacture aneta portion of which terminates in a point, and a ll- ALBERT G' SCHMIDT' 5 ing for said net consisting of a plurality of lVitnesses:
